Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589828, here are decompositions:

97 + 31589731 = 31589828
367 + 31589461 = 31589828
421 + 31589407 = 31589828
499 + 31589329 = 31589828
541 + 31589287 = 31589828
577 + 31589251 = 31589828
631 + 31589197 = 31589828
661 + 31589167 = 31589828

Showing the first eight; more decompositions exist.
